Let's divide 6223 by 86
We want to divide 6223 by 86.

Step 1:
86 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 86

Moving on to step 2:
If we divide 62 by 86, we get 0 and a remainder of 62.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 62 to get 62.
Bring next digit (2) of the dividend behind the 62 and repeat the process: 622 / 86

Advancing to step 3:
86 goes into 622 7 times with a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 602 away from 622, we end up with 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 86

Advancing to step 4:
If we divide 203 by 86, we get 2 and a remainder of 31.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
Deduct 172 from 203 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 5:
When dividing 310 by 86, we get 3 with a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 72.3
The remainder is 52 after subtracting 258 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 6:
The number 86 fits into 520 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 72.36
If we take 516 away from 520, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
If we divide 40 by 86, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 72.36
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
If we divide 400 by 86, we get 4 and a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 72.3604
Subtracting 344 from 400 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 9:
86 goes into 560 6 times with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 72.36046
Subtracting 516 from 560 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
440 divided by 86 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 72.360465
Subtract 430 from 440 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
The number 86 fits into 100 1 times, leaving a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 72.3604651
If we take 86 away from 100, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
If we divide 140 by 86, we get 1 and a remainder of 54.
The next digit of our result is 1. 
Result so far: 72.36046511
If we take 86 away from 140, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 72.36046511 with a remainder of 5.4e-08.
